2. SWM341是M33内核，JLINK需要V9以上版本，KEIL需要5.32以上版本。
1、使用USB功能时，晶振需要接 12MHz
4、LCD的RGB888和LCD CLK/HS/VS/DE不要更改
5、USB的DP DM需差分按USB协议走线，1.2V可由MCU1.2V提供，加滤波
6、在上电时检测到 ISP是高电平，将进入 ISP BOOT烧录模式
7、RGB尽量等长走线， RGB间地隔离信号
8、使用停止模式唤醒时， WAKEUP口都需要上拉
10、ISP模式烧录的串口正是 SWD的烧录口 TX0 RX0；打印信息是M0 M1
3、如果IO不够，SD_DET可用作别的功能，SD卡用软件通讯检测
9、N4 N5的I2C或CAN可以兼容5V的电平。
